6x^3 + 3x = 3x(2x^2 + 1)
It is (x+5)(x+1) when factored
It is (x+6)(x+7) when factored
8^3 = 8 x 8 x 8 = 64 x 8 = 512
X2 + 4xx(x + 4)=======
6x^3 + 3x = 3x(2x^2 + 1)

Factorise it: (x + 5)(3x - 8)
x(x+5)
x + x = x(1+1)
(x + 2)(x + 1)
x3-16xx(x2-16)x(x+4)(x-4)...forgot to finish it, sorry.
(x+5)(x+3)
It depends on what you wanted to do - graph it, solve it, factorise it, etc.
X=5
It is (x+5)(x+1) when factored
It is (x+6)(x+7) when factored
